Comment 11 for bug 1497688

I installed the version of apt from trusty-proposed as seen in /var/log/dist-upgrade/apt-term.log:

Preparing to unpack .../apt_1.0.9.7ubuntu4.2_amd64.deb ...^M
Unpacking apt (1.0.9.7ubuntu4.2) over (1.0.1ubuntu2.11) ...^M
Processing triggers for man-db (2.6.7.1-1ubuntu1) ...^M

The upgrade from Trusty to Vivid proceeded without error. From /var/log/dist-upgrade/main.log:
